Know your gear

The sleek, new 3S delivers high efficiency and energy-saving battery backup and surge protection for your premium home and office equipment - ready to go right out of the box.

The plug-and-play functionality of the 3S allows you to start backing up your equipment the moment you take the unit out of the box. Gain automatic integration with Windows, Mac and Linux with a simple connection to a USB port.

The 3S manages your energy efficiency for you with EcoControl Master/Control outlets. When the item using the Master outlet (e.g., your computer) is idle or shut down, then items using the Control outlets (e.g., printer, scanner, fax) are automatically powered down - rewarding you with up to 30% in energy savings over a typical battery backup.

The sleek design of the 3S allows you to display it alongside your high-tech equipment for a sophisticated look. This unit can also be wall- or desk-mounted for additional space savings.

The high-efficiency design of the Eaton 3S provides premium power protection for up to 10 devices, including those using data lines.
